Journal of Reliability, Maintainability and Supportability in Systems Engineering






!e Department of Defense (DoD) is responsible for the development, procurement, introduction, integration, maintenance, upgrading, and retirement of all defense and related support systems. To facilitate this task, enterprise-level system architectures are used to describe capability, operational capability requirements and lower level system architectures are used to describe the functionality of system solutions which are necessary to satisfy those operational capability requirements. To ensure the attainment of the required capability solution on time and under budget, systemengineering processes are mandated to ensure consistency and rigor across all participating organizations. However, even though architecting is necessary to insure that all understand user requirements in the same way (providing logical rigor, structure, semantic and syntax), the practice of architecture is sometimes set aside as being unimportant, and programs sometimes fail for lack of good requirements. Defense engineering leadership understands this problem, and the DoD now has the challenge to determine how best to harmonize enterprise/systems architecting practices with systems engineering practices.
